Nothing happened.
“The system has no power,” Darius said.
“It has power.”
Mara pressed her thumb into a nearly invisible recess.
A needle sampled her blood.
The panel illuminated.
Roman raised an eyebrow.
“Your mother was cautious.”
“My mother believed passwords were invitations.”
The door opened into a cylindrical chamber beneath the lighthouse.
Rows of servers stood behind glass walls. Blue lights awakened one by one as Mara entered. A central console rose from the floor.
For the first time since the kidnapping, she felt something close to control.
Tideglass recognized her.
WELCOME, ARCHITECT.
The words appeared on the console.
Mara immediately dismissed them so no external display remained active.
“Can you stop the succession transfer?” Roman asked.
“I can suspend it.”
She entered a sequence of commands.
The system requested behavioral authentication.
Mara followed a moving light with her eyes, repeated randomly generated numbers, and placed both hands on a pressure-sensitive panel.
ACCESS DENIED.
She stared at the message.
“That is impossible.”
She tried again.
ACCESS DENIED.
Keira connected an analyzer.
“Someone changed the primary architect profile six hours ago.”
“They cannot do that without entering this vault.”
“What about a secondary administrative channel?”
“There isn’t one.”
Roman walked around the console.
“Could your mother have created one?”
“She built the system to prevent secret authority.”
“People sometimes build exceptions for themselves.”
Mara opened the oldest source files.
A hidden directory appeared beneath the original operating structure.
Its name was ORPHEUS.
She had never seen it.
Keira whistled.
“That is not a back door. That is a private highway.”
Mara opened the access log.
One authorized user had entered Orpheus repeatedly during the past thirteen years.
V. ELLISON.
Vivienne.
“That cannot be right,” Mara said.
Roman stood beside her.
“Your sister had access.”
“She was fourteen when the lighthouse was sealed.”
“Your mother may have created the profile for later use.”
“She never understood software.”
“Perhaps she understood people.”
A new message appeared.
Incoming private channel.
The screen showed only audio waveforms.
Mara accepted the connection.
Vivienne’s voice filled the chamber.
“Mara?”
Mara gripped the console.
“Where are you?”
“I don’t know. Lucian moved me after the press conference. The windows are covered.”
“Did you give him access to Tideglass?”
“No.”
“Your profile entered the Orpheus directory.”
“I know.”
Mara looked at Roman.
“How?”
Vivienne began to cry, but she forced the sound under control.
“Mom showed me the lighthouse before she died. She said there might come a day when everyone believed you were gone.”
Mara felt suddenly cold.
“Why would she say that?”
“Because Greyhaven was not an accident.”
Roman moved closer to the console.
Vivienne continued.
“Mom discovered that Dad and the Crowes were testing V-17 in civilian cargo cells. The catalyst became unstable near seawater. Gabriel Sable found falsified safety reports and contacted her.”
Roman’s face became stone.
“She planned to expose them,” Vivienne said. “Dad learned about it. He ordered the laboratory cleared, but Lucian’s father wanted the evidence destroyed.”
“The fire,” Mara whispered.
“They expected the building to be empty.”
“We were inside.”
“I followed you there. You told me to stay home, but I wanted to see what you were doing.”
Mara remembered Vivienne appearing in the lower corridor, angry and frightened because Mara had refused to take her to a concert.
For thirteen years, Mara had believed her own disobedience had placed them in danger.
“Mom created Orpheus because she thought they might target you again,” Vivienne said. “It transfers control to me only when the system believes you are dead.”
“Why didn’t you tell me?”
“Dad said the truth would destroy the family. He said you already hated looking at the scars, and knowing why the fire happened would destroy you too.”
“So you agreed to lie.”
“I was fourteen.”
“You are twenty-seven now.”
Vivienne’s breathing shook through the speakers.
“Yes.”
The answer contained no defense.
Mara closed her eyes.
“Why are you marrying Lucian?”
“Because he discovered Orpheus. He threatened to reopen the Greyhaven case and make it appear that Mom caused the explosion. He said Roman would kill our entire family if he learned Gabriel died because of her.”
Roman leaned toward the microphone.
“Your mother tried to save my brother.”
Vivienne went silent.
“He knew,” Roman said. “Gabriel called me. He said Evelyn Ellison had found proof. He went inside to help her recover it.”
“My mother was there?” Mara asked.
Vivienne whispered, “She died three months later.”
“Cancer.”
